I don't have a dog in this fight, since I have no idea what it's about, but as Chuck mentioned, Dan is Dan, and you're not the first to be on the receiving end here. In fact you're in good company. And although he may have chosen that avatar to piss you off, you can exercise the choice not to be pissed off about it. Hell, rostasi had that avatar months ago and nobody was pissed about it. Just a little grossed out, in my case.
